Login failed

Hi SRM MDM Gurus,

I am working on SRM MDM Catalog 1.0.

I am able to login to http:// : /webdynpro/dispatcher/ sap.com/tc~mdmsrmui/MDM_SRM_UI_App with user 'Master' having UI Configuration Manager roles (required to acces to the configuration options).

I can configure the Search UI (OCI mapping, customizing Catalog users).

I'm facing this problem. When I login to the http://<server>:<port>/SRM-MDM/SRM-MDM

using users with the Catalog user role i am getting "Login Failed" error.

On the whole i am unable to see the SRM MDM Webdynpro catalog.

What has to be done now?

Is there any bug in the SRM MDM Catalog?

I'll reward points for help

Thanks in advance

Gg
